Using a tap to cut threads?! I know, crazy, right? But just you watch! In a pinch you can use a smaller tap of the right pitch to thread larger bores than the tap was intended for.
Soo your telling me you take a tap that’s the same thread per inch as the print ask for setting the feed rate as the threads per inch and moving it in just like you would a boring bar is that what your doing?? I’m a machinist and I never seen this in my life if it really works I love to know I more
FYI: You're Not Limited to running the same Thread Pitch if you grind off all but one point (per flute so you can still rotate it to a good one if not brazed in place {or if using a 4 flute tap}) effectively turning the tap into a Single Point Threading Tool with all of the Clearances Built In. . . I've done that many times over the years with old broken taps making mini boring bars (and internal Chamfer Tools) out of them.
I invented this as well as quotation marks the number 5 and spousel abuse oh yeah and the thing where you scratch your head while you're thinking YOUR ALL WELCOME and I almost forgot I invented the phrase you're welcome as well so you're welcome for you're welcome
I have single point cut stuff much smaller for my previous job making electron microscope parts lol. You employ the 'cut fresh air' method with multiple passes method to your arsenal.
Maybe its just for me a stupid Question, but you said that u brazed your Tap on. Is there a difference between brazing and welding for example a tap on, and if yes what is the difference ?
I generally never use machines of these sorts. I probably never will. Your videos are exceptionally satisfying for me to watch, and the corny jokes are absolutely glorious. Neat fucking channel Old Tony.
Awesome trick. Ive been trying to think of a decent way to make custom attachments that thread on to porta power rams. I think this may be the trick I need.
What you did here is called combing. Nothing new under the sun. If the tool was spinning, you’d speak of whirling a thread. Greetings, a fellow turner-machinist
I had a need to cut an internal differential thread combo (30 TPI/40TPI) in a 1/4" bore. I fashioned my cutting tool by grinding away all but one "tooth" of a 5/16-18 tap, removing the balance of the tap enough to give the clearance needed inside the bore. Rather than braze or silver-solder the tool to a square shank, I clamped the unground tap shank into a small boring bar holder.
1"-24 UNS tap is about $38, unless you want to take your chances with Ebay at $18. I don't know what you consider expensive for tooling, I can't afford a machining hobby. Yet.
i like the triple antler spinner insert kajigger, that way if you chooch a hootenanny while you're twirling you can just frig sack the spinner and keep on keeping on with out screaming F, scaring the kids, pissing off the wife and re chooching but you can only twirl threads in accordance, on accounta the cigarette butts
All this time subscribed to This Old Tony I thought I was watching a machinist with a quick wit...really, I was just watching a heavy-metal, quick-witted, hand model.
You're only cutting with the first thread so cannot see any advantage over a single point tool. If he'd of shown cutting a large thread in steel using a taper tap so you can go straight to depth it would have been a better video.
A million is on the way cutie Jk... I love your videos Tony and a million is on the way Ps. Your still cute Pss. To your wife Psss. Probably Pssss I'm just a drunk guy on the internet. Keep up the good work
Hey Mr Old sir, as your gonna be a millionaire soon, any chance you can take a hit on a China milling machine to go with the Manila the . I promise to; like comment, and if the video is any good, subscribe. :) Seriously tho, loving your vids btw longtime fan.
This not only helps with my internal thread taps. But my internal feelings, which seemingly correspond to my taps.. a total mess, but kinda work once, if I apply enough force at the start but honest enough to accept I made a mistake later...

I got a question as far as this subject goes. Isn't a lathe a risky way to cut threads? More so referring to multi pass process. Just seems like it would be able to cut different(secondary) threads especially in the beginning, unless the plunge is timed with the rotation. Perhaps lathes are built that way?
"As the bores get smaller, it gets harder, and harder to breathe. Obviously, you're going to need a smaller tool ." If I had a quarter for every time I've heard that.
Tony, long time viewers must know that you are a closet air rifle shooter and motorcycle rider. Then you must also be a catch and release fly trout fishermen. I of course am all of the above but never release anything. The most overpriced Items I have run across lately are the rotary fly tying vices. Please address this item and come up with a diy superior vice that can be made in our home shop.
Hey TOT Been watching you since before forever existed, I just recently started my machining channel more serious like while I don’t wanna mooch off your success if you’re feeling nice a shout-out to a fellow metal man would be kindly loved and appreciated ❤️ Much love From Canada! PS If anyone says making videos is easy they’re mistaken.
Hi I'm a machinist of 35yrs exp, personally I grind from old endmills, With single tooth, therefore I can cut any pitch, and dia on lathe or mill. thx for another cool 😎 trick!
You just gave me an idea. What if you built a floating holder for the tap that allowed the spinning part the pull the tap in. This would then not require any lathe settings to change thread pitch. I have used floating tap holders on mills but I wonder if it would work on something like this.
It would appear to me that swarf is cutting along the length of the tap, that tells me the tap is not square to the axis. What you need to do is grind away all but two of the teeth to prevent this.
Love these tips videos. I'm sure it takes 2021 years to come up with each new tip series. Please don't feel like you have to show us something new though. I just love to watch you play. Would love to just watch a ToT live-stream of you cursing at your machinery.
If you braze the tap into the center of a piece of hex stock for a 3 flute, or square stock for a 2/4 flute, you can use all the flutes as cutting edges over time and still use them as a standard tap.

I wish I was clever enough to come up with a funny comment. Not that guy, me. My question is how did you keep from de-tempering the tap after brazing it into that big block of steel for holding it in your tool-post holder?
